# Scrabble Score

Given a word, compute the scrabble score for that word.

## Letter Values

You'll need these:

```plain
Letter                           Value
A, E, I, O, U, L, N, R, S, T       1
D, G                               2
B, C, M, P                         3
F, H, V, W, Y                      4
K                                  5
J, X                               8
Q, Z                               10
```

## Examples
"cabbage" should be scored as worth 14 points:

- 3 points for C
- 1 point for A, twice
- 3 points for B, twice
- 2 points for G
- 1 point for E

And to total:

- `3 + 2*1 + 2*3 + 2 + 1`
- = `3 + 2 + 6 + 3`
- = `5 + 9`
- = 14

## Extensions
- You can play a double or a triple letter.
- You can play a double or a triple word.


## Getting Started

For installation and learning resources, refer to the
[exercism help page](http://exercism.io/languages/haskell).

## Running the tests

To run the test suite, execute the following command:

```bash
stack test
```

#### If you get an error message like this...

```
No .cabal file found in directory
```

You are probably running an old stack version and need
to upgrade it.

#### Otherwise, if you get an error message like this...

```
No compiler found, expected minor version match with...
Try running "stack setup" to install the correct GHC...
```

Just do as it says and it will download and install
the correct compiler version:

```bash
stack setup
```

## Running *GHCi*

If you want to play with your solution in GHCi, just run the command:

```bash
stack ghci
```
